I purchased an Italian Wine Corker over the internet for $130 as this was supposed to be a big upgrade, per my friend John, over the $50 model.  Ended up I had a defective one and the corks did not go in straight.  In addition, I learned that if you don’t have fresh corks, they will always go in poorly with dimples on top.  After wasting about 20 corks, I sent this one back and rented a corker from the Beverage People in Santa Rosa.  It worked like a charm! and for only $10/day.
